如果是按照以前老版本xml的方式来实现：底部导航栏、顶部toolbar、悬浮按钮floatingActionButtonPosition，代码会比较多而且很难懂，现在我们来看看使用神奇的compose来实现，效果图：

代码：

@Composable
fun MainPage() {//当前选择的NavItemvar selectIndex by remember { mutableStateOf(0) }val navTextList = listOf("主页", "发现", "我的")//图标val iconList = listOf(Icons.Default.Home, Icons.Default.Favorite, Icons.Default.AccountBox)Scaffold(topBar = {TopAppBar(navigationIcon = {IconButton(onClick = {}) {Icon(Icons.Filled.Menu, null)}},title = {Text("stars-one的测试应用")},actions = {IconButton(onClick = {}) {Icon(Icons.Filled.Share, null)}IconButton(onClick = {}) {Icon(Icons.Filled.Settings, null)}},
//                backgroundColor = colorResource(id = R.color.purple_700))},floatingActionButton = {FloatingActionButton(onClick = { /*TODO*/ }) {Icon(imageVector = Icons.Default.Add, contentDescription = null)}},bottomBar = {
//            BottomNavigation(backgroundColor = colorResource(id = R.color.white)) { // 底部背景颜色BottomNavigation {navTextList.forEachIndexed { index, str ->BottomNavigationItem(label = { Text(str) },selected = index == selectIndex,//选中选项的颜色 (text\icon\波纹)selectedContentColor = colorResource(id = R.color.white),//未选中选项的颜色 (text\icon\波纹)unselectedContentColor = colorResource(id = R.color.black_bottomnav),// 默认为true,底部的字未选中时是否显示alwaysShowLabel = false,onClick = { selectIndex = index },icon = {Icon(imageVector = iconList[index], contentDescription = null)})}}},//注意此参数,可以实现图中那种被裁剪的效果,前提是上面的cutoutShape也有设置floatingActionButtonPosition = FabPosition.End) {//这里是主界面//根据底部导航选中的下标改变展示的页面when (selectIndex) {0 -> Text("这是首页")1 -> Text("这是发现")2 -> Text("这是我的")}}
}

是不是很简单，这样就可以了，谢谢观赏
